Tolay Lake Regional Park open to the public

After years of limited public access only on weekends, Sonoma County’s largest park is now open to all, daily.

Located southeast of the town of Petaluma, the 3,400-acre Tolay Lake Regional Park is a truly unique setting. The park includes much of the Tolay Creek watershed, and provides habitat for a variety of animals and birds, especially raptors. It currently features 11 miles of trails crossing rolling grasslands and open ridges, which offer views of San Pablo Bay, the San Francisco skyline, and Bay Area peaks.

The park is named for the 200-acre seasonal lake that forms in the valley between its ridges — the largest natural freshwater lake in Sonoma County. Tolay was a spiritual center for the local Coast Miwok tribes as well as Native Americans from throughout California, making it one of the most significant Native American cultural areas in California, according to park planners.

The park was created as collaboration between Sonoma County Regional Parks, the Federated Indians of Graton Rancheria, Sonoma County Agricultural and Open Space District, and Sonoma Land Trust. The plan is to create a total of 30 miles of trails, hike-in campsites, a visitor center and bunkhouse, outdoor classrooms, equestrian amenities, and new picnic areas, restrooms, and parking.
